Ye Old Animation Studio Photo circa the F.D.R. Administration.
Right image: Same guys, different positions.
The photo is pre-digital photoshop trickery that falls a little short in this combination of two photos featuring the same guys. Harry Love gave a lot of photos to board artist Bob Foster back in the 70s at Hanna-Barbera, and he provides one of them to TAG blog. Says Bob:
I touched the picture up a little in Photoshop, but some of the overlapping images were just too complex to mess with. I added the "split."
* To most Boomers "Screen Gems" means Columbia Pictures' old television production division. But before Screen Gems T.V., there was Screen Gems the animation studio. The division didn't last long, but it employed a number of animation heavyweights in its brief lifespan.
** Most likely not Givens, as it seems that B.G. never worked at Screen Gems.
